A hypervisor is a software program that allows multiple operating systems (OS) to run on the same physical hardware as virtual machines (VMs). A hypervisor can be classified into two types: Type 1 and Type 2. A Type 1 hypervisor interacts directly with the hardware and does not need an underlying OS to function. A Type 1 hypervisor is also known as a bare-metal hypervisor or a native hypervisor. A Type 1 hypervisor can manage storage, network, and VMs more efficiently and securely than a Type 2 hypervisor89.
